TL3474ACD Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with the TL3474ACD placed close to the power supply bypass capacitors. The input and output capacitors should be placed as close as possible to the device pins. A ground plane is also recommended to reduce noise and improve stability.
  • The output capacitor value and type depend on the specific application requirements. A general guideline is to use a capacitor with a value between 10uF to 100uF, and an ESR (Equivalent Series Resistance) of less than 1 ohm. X5R or X7R ceramic capacitors are recommended for their low ESR and high reliability.
  • The TL3474ACD has an absolute maximum input voltage rating of 18V. However, it's recommended to operate the device within the recommended input voltage range of 3.5V to 16V to ensure reliable operation and prevent damage.
  • To ensure stability, follow the recommended layout and placement guidelines, use a sufficient output capacitor value, and ensure the input voltage is within the recommended range. Additionally, adding a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins can help to reduce noise and improve stability.
  • The typical dropout voltage of the TL3474ACD is around 1.5V. This means that the output voltage will be approximately 1.5V lower than the input voltage when the device is operating in dropout mode. This should be considered when designing the power supply and selecting the input voltage to ensure the required output voltage is achieved.
